This is chaos: Jeff Goldblum runs from T. rex in wedding photo

The essence of chaos theory, "Jurassic Park" fans, is that there is no predictability in complex systems. So when Jeff Goldblum attends a wedding (arguably a complex event), what we think will happen may not.

The actor, who starred as cocky genius Dr. Ian Malcolm in the 1993 blockbuster, stars again in another dinosaur hit, this time as part of a viral image of a wedding party running away from a Tyrannosaurus rex.
